Description

The SIPROTEC 7SJ62 relays can be used for line protection of high and medium voltage networks with earthed (grounded), low-resistance grounded, isolated or compensated neutral point.With regard to motor protection, the SIPROTEC 7SJ62 is suitable for asynchronous machines of all sizes. The relay performs all
functions of backup protection supplementary to transformer differential protection.
7SJ62 is featuring the "flexible protection functions". Up to 20 protection functions can be added according to individual requirements. Thus, for example, a rate-of-frequency-change protection or reverse power protection can be implemented.

The relay provides control of the circuit-breaker, further switching devices and automation functions. The integrated programmable logic (CFC) allows the user to implement their own functions, e. g. for the automation of switchgear (interlocking). The user is also allowed to generate user-defi ned messages.
The flexible communication interfaces are open for modern communication architectures with control systems.
